C influenza, in contrast to the natural mutation of a single strain, known as antigenic drift

D influenza, different than antigenic drift, which refers to the natural mutation of a single strain of influenza

E influenza; in contrast to antigenic drift, which refers to the natural mutation of a single strain of influenza

OA: A. 求大神解释原因。以及E选项中，如果分号改成逗号的话，正确吗？感谢！

Antigenic shift refers to the combination of two different strains of influenza;
（in contrast,） antigenic drift refers to the natural mutation of a single strain of influenza.

这样看，你不觉得A没有错误，而且用了很完美的平行，而且完全表达了需要表达的意思吗？

主谓宾就表达清楚了的句子，为什么要用E里的,which呢

分号后面一般都是接另一个完整的句子，E选择中，明显分号后面加的是fragment，而不是一个完整的句子
